[EDIT] (in reponse to OP revised question)
I've been following the literature for quite a long time. I don't think there's a "program slicing" central that has a list of the kind you want. Most of the program slicers that have been built were some kind of university experiment (means they didn't work in production and aren't available for practical purposes). You can find out about them by searching scholar.google.com with the term, guess what, "program slicing"; I suspect you already know this. The "biggies" I think you already have here.
This survey is bit old but done by a stellar researcher: http://www.cse.buffalo.edu/LRG/CSE605/Papers/slicing-survey-tip.pdf. This one is more recent:

CodeSurfer is a commercial tool for performing static slicing on C programs. I believe they also handle C++. A significant plus not available with other tools is a UI for exploring code slices interactively.
Indus is University research tool for doing static code slicing on Java. I'm not sure if this is still under active development.
There seem to be a variety of "dynamic" program slicing tools for Java built by universities. None of them are under active development or use that I know about.
My company offers the DMS Software Reengineering Toolkit, which contains general machinery for program control and data flow analysis including building custom static code slicers. DMS has been used to build slices of large C programs as well as industrial process control programs. (I'd provide a link, but SO people seem to hate it when I do).
